| 摘要: |
| 以比转数（ns）、相对流动角（arctan（a/v））和水泵零流量全特性参数为自变量，对离心泵全特性曲线进行了描述，并提出了离心泵全特性曲线预测线性回归模型。对比检验结果表明，该离心泵全特性预测模型是可靠的。 |

| Abstract: |
| By using specific speed (ns),relative flowing angle (arctan(α/υ)) and complete characteristic parameters of zero flow rate as independent variables,complete characteristic curves of centrifugal pumps are described and a linear regression prediction model of the complete characteristic curves of centrifugal pumps is put forward.Comparison between prediction values and test results of a centrifugal pump indicates that the prediction model is reliable. |
| Key words: centrifugal pump complete characteristic curve prediction model |
